Specification of Letters Phtont. Application fled. December 18 1901,

residing at 73 Lydenhmn Hill, (-amhcrwcll,

county of Kent, En land, have invented certain new and use ul Improvements in Counter-Current Condensers, fully described and represented in the following spe fication and the accompanying drawings. forming a part of the same. lhis invent-ion relates to jet ma n-users of that class known as counter corrl-nt condensers, the object of the invention bring to provide an improved crim'lcn=cr that shall secure an ellicicnt condensation and high vacuum with a small amount of condensing" water and avoid reversal of the (urn-lit, aridfurthcr to rovide an improvcd constrfiction for taking all and cooling the air.

For a full understanding of the infi-ntion, 8. detailed description of a condenser embodying all the features of the same f: their prefcrred form will now be given in connection with the accompanying drawing forming a.

art of this spccilicatiuh; and the features ormmp the invention then specifically pointer out in the claims.

In the drawings-----Figurc l is a vertical central scction ol' the condenser. F igs. .2, 3 and 4 are cross sections of the same on re-' spcctivcly the lincs 2, 3 and 4 of Fig. l.

Rcl'crrm to the drawings, A is the condenser shell, B the exhaust steam inlet, C the discharge outlet, 1) the injection or condcnsin water inlet and E a series of outer travs iiltcrnating with a series of inner trays F through which the condensing water passes downward-froin the inlet D at the top of the condenser to the outlet C .at the bottom of the condenser. These trays E, F, have their bottoms provided with elongated openings 10 through which the water falls in elongated jets from one tray to the next through the series, the outer trays E bein inclined so that the jets are thrown inwart into the inner trays F, and the inner trays F heingjnclincd outward so that the jets are thrown .outwnrd into the outer't-rays, and space is left between the inner and outer trays and between the inner trays and the casing A for the flow of the steam and air u ward through the condenser and between t e oval-water jets in a zig-z path, .as shown by the arrows in Fig. l. 'i ne exhaust inlet B opens into asteam chamber G sur- 5 in; properly distributor chamber, and partially condensed by the Patented Sept-22,1908. sci-m No. 400,9,

.5 rounding a sleeve ll open atthe. bottom within the bottom tray 1, the steam chamln-:- (2 dieing closed at the top, so that the cxha'ost steam passes downward around the bottom of the sleeve l] and through the lowest water jets to reach the interior of Ibo condensing chamber the steam thus'be-- l to the condensing lowest jets. I The air cooler consists of a chamber I in the upper part of the condenser having u wardly extcnding' pipe K to which the air pump is connected, the air entering this chamber I at the top through mas age 11.70 l'oruicd' bctwccn the inner portion of (he to tray l: and the open top of the clmmbrir thr condensing water entering a sleeve 12 Enclosing the pipe K'so as to cool the latter and being thrown into the chamber I from openings 1 in the sleeve 12 and dellcctcd from surfaces 2 on the chamber and sleeve so. as to provide u'scrics of jets by which the air is cooled and any un'conderised steam condcnscd. The discharge water from the chamber I passes downward through drain pipe. 13 arranged centrally of the condenser, this pipe being scaled atjts lower end by water vessel '14 carried by the lower end of the pi 9, so that no steam from the lower '85 i part 0 the condenser can pass direct to the air cooler, and b the ion discharge pipe a considerable di erence of prcssures can set up without interfering withthe proper drainageof the air cooler.

The 0 erntion of the condenser is as fol-- lows-ii flow a, condensing water havin been cstahlished,'the steam enterin at B 18 distributed around the sleeve G in t e chamber H, and asses downward around the lowcncnd of t e sleeve and through the was tcr jets from the lowest tray E into the central opening inclosed by the tray and then upward between the successive water jets in the path shown b the arrows, to the top of, the condenser. ny air an uncondensed vapor, after Ipassing through the 'ets from the top tray passes inward and. ownward aronn the open top of the chamber I through the air cooler water jets, completing the condensation of the va or, and the air is then drawn 'otf through t e ipe K, being cooled further by the walls-o this pipe inclosed by the co (1 condensing water. The drainage from't a air cooler passes down 110 through the ipe 13 and its water sealed lower end to t he condenser discharge C.

it will be understood that the invention is not limited to the exact.- form or arrangement 5 of the devices shown, but that various moditit-at ions may be made therein without departing from the invention as defined by the. claims.

What is claimed is:---

I. A counter current condenser having a. water inlet above the. condensing chamber, a series of inner and outer trays provided with openings forming nter jets between which the Sitnlll passes. a steam inlet in the lower ")5 part of the condenser, and a steam distributing sleeve op iosite the steam inlet forming a steam inlet c nnnber surrounding the condcnsing chamber and open at tho bot-tom to the condensing chamber.

'2. A counter current condenser having a water inlet above the condensing chamber, :1 series ol inner and outer trays provided with elongated openings forming narrow water jets between which the steam passes, a steam inlet in thelower part of the condenser, a steam distributing sleeve 0 positc the steam inlet forming :1 steam in ct chamber surrounding l-he condensing chamber and n on at the bottom -to the condensing chum icr, the bottom water tray being placed at the lowcrcnd of the sleeve and inclosing the opening through which the steam passes upward to the con lensing chamber. 2

3. 'A counter currentcondcnscr having a water inlet at the top and a. steam inlet at the bottom, a series of water trays provided with openings to form water jets between which the steam passes u )ward, an air cooler and supplementary condenser at the top of the condensing chamber, and a drain ipo for the air cooler extending downward t irough the condensing chamber.

h 4. count-er current condenser having a. water inlet attho top and a steam inlet-at the bottom, a series of water trays provided with o enings to form water jets between which te steam passes upward, an air cooler and supplementary condenser at the top of the condensing chamber, connections for spray ing condensing water into said cooler, and a drain pipe. for the an cooler (L tton-din do vnward through the condensing chamlicr and water scaled atits'lowcr end.

5. A counter current. condenser having U1 its upper part it chumbcrrcce-ivin the air andnncondcnscd steam and coolod y the con dcnsing \vnlcr, an air delivery pipe from said chamber, and a water discharge ipe from said c-lu'unber extending downwnn through the condensing chamber and water sealed at its lower end.

i). A counter current condenser having a series of outer and inner trays E, F, harm their bottoms inclined .and rovidcd witopenings elongated radially o the condenser to provide narrow water jets between the trays.

7. A counter current condenser havin in the upper part of the condenser the chain or I open at the top to receive the air and uncondensed vapor, sleeve 12, int-losing said chamber, and connections for supplying con- (lensing water to said sleeve.

8. A count-er current condenser havingin the upper part of the condenser thechamher I open at the top to receive the air and imcondensed vapor, sleeve 12, inclosing "saigl chamber, connections for supplying condcn ing water to said sleeve, and openings 1 and tending downward through the conden chamber and water sealed at its lower end.

In t-estimon whereof, I have hereunto set my hand, in t a presence of two subscribing witnesses.
